Handling the analytical unit

The CoreSense M10 analytical unit weighs 65 kg (144 lb). It is not designed to be installed by one
person. At least two people should be installing this unit.
To avoid personal injuries, make sure to follow the proper lifting and carrying instructions when
handling the instrument.

Handling the sensor head

lifting and carrying instructions when handling the instrument.
WARNING
Do not grab the sensor head by the mounting threads. Thread edges are sharp and pose
a risk of personal injury.

Avoid touching the surface of the mounting interface.

Electrical safety

WARNING
Failing to comply with any of the instructions, precautions or warnings contained in this
manual is in direct violation of the standards of design, manufacture, and intended use of
the instrument.
ABB assumes no liability for the user's failure to comply with any of these safety
requirements, which may result in personal injuries and/or instrument damages.
ONLY qualified personnel may perform the electrical installation of the monitoring system.
In accordance with international safety standards, the monitoring system uses a three-wire power cord
or line typically connected to an electrical panel that provides grounding for the monitor chassis.
• CoreSense M10 is an overvoltage category II instrument.
• An external circuit breaker with a 8 A rating or less must be installed on the AC source and labeled
in compliance with your country's national electrical code. Also, if required by this code, a circuit
breaker or switch in the building installation, marked as the disconnect switch, shall be in close
proximity to the equipment and within easy reach of the operator.
• Before opening the analytical unit cabinet, cut power at the distribution panel circuit breaker.
• Ensure that the equipment, and any device or power cord connected to the analytical unit, is properly
grounded.
• Make sure that the analytical unit earth is at the same potential as the transformer earth.
